Definitions

• This invention relates to a multi-part closure device made of plastic, consisting of closure cap, lower part and not continuous circular cutting ring as a central element, and which can be attached via a Sollöffhungsstelle a closed container or on a bottle neck.
• containers For storage of flowable media, various containers are available in the market, in which before opening a membrane, film or the package wall itself must be pounded before the liquid medium can be removed from the container.
• Such containers may be soft packaging made of multilayer cardboard or films, to which a closure device is glued or welded. But it can also be bottles with a threaded or Aufschnappstutzen, in which a film on top of the neck closes the bottle, and then this film must be cut.
• Typical closure devices for such types of packaging have a lower part with a cylindrical spout and an outer thread and a lower edge flange for attachment to the soft pack.
• the closure lid Before the contents can be removed from the container, the closure lid must be unscrewed from the base to cut through the container wall in the area of the spout.
• the opening of the container wall at the Sollöffhungsstelle can be done by finger pressure on the integrated piercing, but has the disadvantage that the Ausgiesseigenschaften such closures are bad and that the risk of contamination of the liquid is large, because the finger comes into contact with the liquid.
• Another way of opening the container wall is to pierce a piercer through the packaging material with the aid of the closure cap.
• the closure must be complete first are turned down to move down the piercer mounted in the spout of the base, whereby the soft package is opened.
• piercers which cooperate interactively with a closure cap in such a way that when unscrewing the screw cap at the same time the piercer is moved so that it is required down and pierces the packaging wall. The severed part of the package wall sticks to the piercer because it has to be adhered to the package wall. The piercer itself remains in the cap and is conveyed out when opening. By repeatedly opening and closing the cap can easily take place multiple contamination of the contents.
• the assembly of this device is delicate and expensive. Since the piercing must be glued to the container wall, the correct dosage of the adhesive is crucial for the successful first opening of the packaging material.
• the piercer is first pressed by elements which are mounted at the bottom of the lid of the cap when it is screwed down so that a cutting member pierces an underlying film and then the piercing is still rotated. Until the rotation is completed and the film Meanwhile, the cap has unscrewed from the nozzle thread and can be removed.
• the cap of the piercer because yes presses the cap with the elements on its underside of the lid when screwing on the piercing, initially pushed a bit further down. This requires a corresponding effort when first screwing the closure and is objected to by the consumer as unpleasant.
• the object of the present invention is to provide a closure device on the one hand, in which the force for opening is lower, and on the other hand, it is the object of the invention, a very accurate, sharp, knife-like cutting of the soft pack or the film on a To guarantee container neck in the Sollöffhungsstelle, and further it is an object of the invention to guarantee at any time a regular, laminar pouring behavior of the liquid ingredient. Finally, it is an object of the invention, with such a closure device, to be able to meter a separate substance, also a sensitive substance, into a container contents by opening.
